6 Claims.

The object of my invention is to provide cork screws which can operate either of two ways, one being the usual method of screwing the device into corks for removing corks that pull out easily and another way for engaging the bottom of corks in the case of corks that stick tightly in bottles. I attain these and other objects of my invention by the means illustrated in the accompanying drawing, in which Figure 1 is a perspective view of one form of cork screw;

Fig. 2 is an elevation of another form of my invention;

' Fig. 3 is a section on line 3-3 of Fig. 2;

Fig. 4 is an enlarged detail view partly in section and partly in elevation of the form of the invention shown in Fig. 2;

Fig. 5 is a transverse section on line 5-5 of Fig. 4;

20 Fig. 6 is a detail of the elevational view of the cork screw applied to a cork in position to extract it; and v Fig. '7 is a perspective view of a modified form of the invention having a detachable handle.

25 Like numerals designate like parts in each of the several views.

Referring to the accompanying drawings, I provide a shank 1 having a thread 2, as shown in Figs. 2, 4 and 5, and a preferably integral ,80 handle 3, as shown in Figs. 1 and 2, the handle having spaced projections 4 for use in removing a crown cap from a bottle. The shank 1 is provided with a reduced end 5 on which a short slotted screw 6 is pivotally mounted by means 85 of pivot 7. This screw is provided with the threads 10 terminating in a point 9 at its lower end and fiat head 13 at its upper end which when alined with shank 1 is spaced slightly from the end portion 14 of the shank 1 to permit of the 40 pivotal movement of the screw section 6.

I provide a sleeve 8 slidably mounted on shank 1 and adapted to releasably engage over the up per end 13 of screw section 6.

In using the device on corks that can be easily removed from a bottle the sleeve is slipped over the upper end of member 6 to hold it in alinement with the shank 1. In this position the cork screw will remove, in the usual way, corks which can be pulled out easily.

For hard and stubborn corks which stick tightly in bottles the sleeve 8 is removed from engagement with member 6 and the cork screw is screwed through the cork C as shown in Fig. 6, and the screw section 6 will swing freely by gravity to a position at right angles of the shank 1 1934, Serial No. 715,515

as the pivot mounting '7 is positioned in a slightly offset position relative to the center of gravity of member 6 so that it will automatically swing to a horizontal position at right angles to the reduced end 5 of shank 1 whereby the member 6 will engage the bottom of the cork in the manner illustrated in Fig. 6 and greatly facilitate its withdrawal and prevent the breaking of the cork.

It is within the contemplation of my invention to provide a detachable handle to be secured by a 10 suitable fastening element such as a rivet through the aperture 12 of the upper reduced end portions 5, as shown in the modification in Fig. 7. The section 6 may be a threaded and partially slotted cylinder as shown in Fig. 1, or it may be a thread- 15 ed half-cylinder as shown in Figs. 2, 4 and '7. As shown in Fig. 4, I may provide a shoulder 11 to limit the movement of sleeve 8. I may attach my cork screw to suitable articles such as knives.

What I claim is: i

1. In a cork screw, the combination of a shank,

a handle, a sleeve slidably mounted on the shank,

a reduced end on the shank, a screw threaded section releasably engaged by the aforesaid sleeve and pivotally mounted on said reduced end and swingable to a position at right angles to the said reduced end whereby the threaded section can engage the bottom of a cork to facilitate removing the cork from a bottle.

2. In a cork screw, the combination of a shank, a handle, a sleeve slidably mounted on the shank,

a reduced end on the shank, a screw threaded section releasably engaged by the aforesaid sleeve and pivotally mounted on said reduced end in an offset relation to the center of gravity of said section, and swingable by gravity to a position at right angles to the said reduced end whereby the threaded section can engage the bottom of a cork to facilitate removing the cork from a bottle.

3. In a cork screw, the combination of a shank having a reduced end, a handle, a screw threaded section pivotally mounted on said reduced end at a position offset from the center of said screw threaded section, whereby said section is swingable by gravity to a position at right angles to the said reduced end whereby the threaded section can engage the bottom of a cork to facilitate removing the cork from av bottle.

4. In a cork screw the combination of a shank, a handle, a sleeve slidably mounted on the shank, the shank having a reduced lower end, a threaded screw section pivotally mounted on the reduced end of the shank at a point offset from the center of gravity of said section whereby the 56 section will automatically swing to a horizontal position when this section of the cork screw has pass ed through the cork, to engage the bottom of the cork and facilitate removalof same.

5.111 a cork screw, the combination of a threaded shank, a handle, a sleeve slidably mounted on the shank, a reduced end on the shank, a screw threaded section releasably engaged by the aforesaid sleeve and pivotally 10- mounted on said reduced end and swingable by gravity to a position at right angles to the said reduced end whereby the threaded section can engage the bottom of a cork to facilitate removing the cork from a bottle.

6. In combination with the device defined in claim 1, the aforesaid shank being reduced at the upper end, and a handle detachably secured to said shank.
